Ziki-set,
I was having the same problem. For some reason the installer isn't altering your forum database tables (_thread & _post). You need to go into your database and physically add the 'dice' field (mediumtext not null) to those two tables.
That fixed the problem for me.

Also, before installing I corrected some wording in the xml file to correct 'dices' to 'die' because it 'bugged' me:
FIND

<td><smallfont><b>Dice roll with $dicesno dices of $dicesfaces faces: $dicepoints points</b></smallfont></td>

CHANGE TO

<td><smallfont><b>Dice roll with $dicesno die of $dicesfaces faces: $dicepoints points</b></smallfont></td>

Also increased the number of 'faces' for dice to 100 since that is what my members needed.
FIND

if ($faces[$i] >= 2 && $faces[$i] <= 30)

CHANGED TO

if ($faces[$i] >= 2 && $faces[$i] <= 100)

Of course I had to 'make' die images for 31-100, and upload them to the ../images/dice folder but that didn't take too long.

Hope this helps

EDIT: 3:30pm CDT
hmmmm, that works up to '99' faces but can't get it to work for '100'..... *wanders off to ponder a bit*

EDIT: 3:47pm CDT
got it to work
FIND:

preg_match_all("/\[dice=([1-5])\]([0-9]?[0-9])\[\/dice\]/",$post['message'],$diceresult);

CHANGE TO:

preg_match_all("/\[dice=([1-5])\]([0-9]?[0-9]?[0-9])\[\/dice\]/",$post['message'],$diceresult);
